The article introduces invariants of a Riemannian manifold related to the mutual curvature several pairwise orthogonal subspaces tangent bundle. In case one-dimensional subspaces, this is equal half scalar subspace spanned by them, and in complementary mixed curvature. We compared our with Chen proved geometric inequalities intermediate mean squared for submanifold. This gives sufficient condit...

using the facts controllers, such as static synchronous compensator (statcom), as it provides continuous reactive power, in the grid including wind turbine (wt) equipped with doubly fed induction generator, for improving voltage profile (under normal circumstances) and providing a transition ability from inductor generator transition state has been proposed. in this paper, in order to control t...

A paging network (see Figure 1) begins at the connection to the public switched network or telephone lines. The caller can initiate a page through voice mail or a paging operator, or can leave a message by entering touchtones from a telephone. Pages are assembled in the paging terminal and sent to the network controller, where they are combined into batches based on their final destination. Bil...

Wireless Sensor Networks (WSNs) consist of small, autonomous devices with wireless networking capabilities. In order to further increase the applicability of WSNs in real world applications, minimizing energy consumption and size are important research topics. A WSN node itself is a complex system consisting of numerous components, and the energy consumption of the node depends heavily on the i...

In this paper, we present the development of a data glove system based on fingertip tracking techniques. To track the fingertip position and orientation, a sensor module and two generator coils are attached on the fingertip and metacarpal of the corresponding finger. By tracking the fingertip, object manipulation tasks in a virtual environment or teleoperation system can be carried out more pre...

This paper describes the results of an experimental and modelling study on hydrodynamics of MellapakPlus packing operated under counter-current gas-liquid flow. The experimental work was focused on measuring the pressure drop, liquid holdup and capacity limit of this packing at specific liquid loads of up to 80 m/m/h. Experimental results for the air/water system confirm that MellapakPlus packi...

Nonlinear numerical simulations are reported for a conventional unitized laminated glass curtain wall subjected to highand low-level air blast loading. The studied curtain wall, spanning floor to floor, consisted of a laminated glass panel, a continuous bead of structural silicone sealant, a split screw spline frame and four rigid brackets. Firstly, a linear elastic FE-model (M01) is presented ...

We propose an analytic, time-variant model that conservatively evaluates the increase in reliability achievable when a component is equipped with a Prognostics and Health Management system of known performance metrics. The reliability model builds on metrics of literature and is applicable to di erent industrial contexts. A simulated case study concerning crack propagation in a mechanical compo...

The Siberian Automobile and Highway Institute presents the results of research on development of the AUTOMATION -EQUIPPED WORKING PLACE OF A CONSTRUCTION ENGINEER (AEWPCE) program package for a personal computer. The complex consists of three main blocks: BLOCK A is the scheduling on the imitation model basis ; BLOCK B is the standard and resource provision ; BLOCK C is the situation management...

The study develops an analytical model of emissions markets equipped with a safety valve mechanism. It examines the regulator’s control of emission reductions by emitters by setting two policy parameters: emission targets and trigger prices. We show that the capabilities of these two policy tools are greatly affected by uncertainty regarding unconstrained aggregate emissions. We also show that ...
